The U.S. economy grew by 2.6 percent during the fourth quarter of 2017, government data showed. Economists polled by Reuters expected growth of 3 percent.

Durable goods orders, however, rose 2.9 percent in December, more than the expected 0.8 percent gain.

President Donald Trump also spoke at the World Economic Forum (WEF) in Davos, Switzerland, on Friday. In a speech, he warned countries against trying to "exploit" other nations through trade and reiterated that he would look out for "America first." However, he aimed to reassure the global leaders that "America first does not mean America alone," and said a strong American economy would lift other countries.

"The dollar is going to get stronger and stronger, and ultimately I want to see a strong dollar," Trump said in an exclusive interview from WEF. "Our country is becoming so economically strong again and strong in other ways, too."
